When CH3CH2MgBr reacts with CO2 which of the following product is formed?
Correct answer: C. CH3CH2COOH
- A. CH3CH2CH2CH2OH
- B. CH3CH2CH2OH
- C. CH3CH2COOH
- D. CH3CH2CH2Br
Explanation
Grignard reagents are highly reactive organomagnesium halides formed by the reaction of magnesium metal with alkyl or alkenyl halides. Grignard reagent is mainly employed as a strong nucleophile in order to react with CO2 directly. This option is correct because the Grignard reagent reacts with CO2 to form carboxylic acid which in this case is CH3CH2COOH.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
